LCD Connector & Contact Configuration
Pitch & Conductor Count
Pitch and conductor count are matched to the contact spacing and circuit count of the target LCD connector.
Contact Orientation
Same-side and opposite-side contacts are available, including Type A and Type D configurations. Contact orientation is specified according to the connector position at the LCD and PCB ends.
ZIF / LIF Interface
The FFC contact section is configured for ZIF or LIF connector interfaces, with contact dimensions and insertion requirements confirmed against the specified connector.
Contact Reinforcement
PET or PI stiffeners can be added to the contact area. Stiffener material and dimensions are specified according to the connector structure and insertion requirements.
Display Assembly & Cable Routing
Cable Length
Cable length is matched to the distance between the LCD module, driver board, and control PCB. Length can be specified according to the available assembly space and routing path.
Conductor Layout
The conductor arrangement follows the required circuit count and connector layout, keeping the cable contact pattern aligned with the display-side and board-side interfaces.
Internal Routing
The flat profile allows the cable to pass through limited internal spaces within the display assembly. Cable length, bend position, and contact orientation can be coordinated with the installation path.
Dynamic Bending
For assemblies requiring repeated movement or adjustment, the specified construction supports 10,000+ bending cycles. Bending requirements should be confirmed together with the installation geometry and operating conditions.
Custom Development & Sample Approval
Drawing / Sample Input
Customer drawings, technical specifications, or existing FFC samples can be provided as the basis for development.
Engineering Review
Pitch, pin count, cable length, contact orientation, connector interface, material, and other required specifications are reviewed for feasibility and material selection before sampling.
Prototype Approval
Prototype samples are checked for dimensions, contact configuration, and electrical performance. The approved sample and specifications are then used for production.
Quality Inspection & Testing
Dimensional Inspection
Pitch, conductor width, cable length, contact dimensions, and overall dimensions are checked against approved specifications.
Electrical Testing
100% testing covers continuity, conductor resistance, insulation resistance, and dielectric strength.
Contact Inspection
Contact direction, exposed contact area, contact dimensions, and terminal positioning are inspected against the approved configuration.
Final Inspection
Finished cables undergo visual inspection, dimensional verification, and final electrical checks before shipment.
Production Consistency & Repeat Supply
Approved Production Reference
Approved samples, drawings, and final specifications are retained as production references for subsequent orders of the same LCD FFC configuration.
Repeat Order Consistency
Pitch, conductor count, cable length, contact orientation, reinforcement, insulation, and connector configuration follow the approved specification for repeat production.
